查询词典 plasma membranes

The animal tests indicated that: the levels of plasma and hepatic LPO were elevated in the rats with hyperlipidemia and hypercholesterolemia and at the same time, the red blood cell osmotic fragility and the concentration of SGPT were also in- creased; when the α-Toc was given, the LPO levels of serum and hepar could be de- pressed, the RBCOF and the level of SGPT were reduced too, which suggessted that the membranes of RBC and hepatic cells might be damaged by LPO.

动物实验表明，具有高脂、高胆固醇血症的大鼠血清、肝组织的LPO亦增高，同时红细胞渗透脆性，SGPT也增高，给予α-Toc可以降低血清和肝组织LPO的浓度，RBCOF，SGPT也下降，提示LPO可能引起了红细胞和肝细胞膜的损害。

Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.

脂质体／水系统和磷脂膜色谱所测定的膜亲和性比正辛醇／水系统的疏水性更好的预测巨噬细胞内药物的α值，因此包含在磷脂膜色谱中但并不体现在正辛醇／水系统中药物与磷脂膜之间的额外吸引性极性作用力对药物在细胞内结合有着重要贡献；药物与有序磷脂膜的结合在很大程度上决定着药物与巨噬细胞内成分的结合，有序磷脂分子膜可能是巨噬细胞内部潜在的结合部位。

During strawberry ( Fragaria ananassa Duch cv.chunxing) fruits maturation,the content of total sugar,anthocyanin and respiration rate increased significantly,and Ca 2+ _ATPase activity of cytoplasm and microsome membrane increased firstly,then peaked at pink stage,and decreased at full red stage in fruits,and also,the activity of plasma membrane Ca 2+ _ATPase was the highest in microsome membranes.

'春星'草莓果实成熟时，总糖和花青苷含量增加，呼吸速率也显著升高；同时，细胞溶质Ca2 + _ATPase活性和微粒体膜的Ca2 + _ATPase总活性变化具有相似的特点，即先升高，至粉红期达到高峰，全红期又下降，在微粒体膜中以质膜Ca2 + _ATPase占的比例最高。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.

对过氧化物酶的细胞定位研究发现，无论抗病杨树还是感病杨树，接种后均发现细胞中有过氧化物酶反应产物，通过分析发现，毛白杨过氧化物酶的活性不仅明显高于未接种的对照，也明显高于接种处理后的北京杨，并且定位更广泛，在细胞壁、细胞间隙、叶绿体膜、线粒体膜及液泡膜上均有大量定位，而北京杨酶反应产物主要分布于细胞壁上，在细胞膜、核膜局部有少量定位，定位范围及强度均小于毛白杨。

Chronic psychological stress can increase GC in Plasma and brain by HPAA. There are plentiful GR on Hippocam--pal cell membranes. It promote presynapitic membrane assoiling EAAs when GC combines with GR.

心理应激通过 HPAA 使血浆及脑组织中的 GC 升高，海马神经元细胞膜上存在丰富的 GR ， GC 与 GR 结合后，可促进神经元突触前膜释放兴奋性氨基酸。

The experiment studies revealed Atom Force Microscope observed vital human erythrocytes that incubated at different temperatures in plasma physiological environment, that surface microstructure of the cell membranes were shapely sensitive to the altered temperature increasingly, and that liquid crystalline state bio-membrane were slightly perturbed and happened phase transition. In the optical tweezers experiment, the captive erythrocytes were encaged in the three-dimensional laser optical potential well, and able to well maintain physiology characteristic property and intact shapes.

实验研究显示，在血浆生理环境中不同温度孵育的红细胞经原子力显微镜观测，其膜表面微观结构对温度变化比较灵敏，液晶态生物膜被扰动而发生轻微相变；在光镊捕获实验中，三维激光势阱囚禁的红细胞却仍能够维持良好生理特性和完好形态，并且细胞膜表面存在相互作用力。

The primary resistances for CO2 diffusion are thought to be at the stomata and at photosynthesizing cells via a combination resulting from resistances of aqueous solution as well as the plasma membrane and both outer and inner chloroplast membranes.

CO2扩散速率的主要限制因素不仅与气孔和光合细胞中它的水溶性有关，还与质膜和叶绿体内外膜有关。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
